Combine Harvest Screen

Our first prototype was with a clear lexan shield.

It seemed to help but not in all conditions. What we found was that in windy conditions, you would get high-pressure at the front of the shield. If you had a large swath coming in along with incoming wind, we were noticing a lot of losses out the sides. This is what steered us in the direction of using screen.

After a few prototypes, we decided on a vinyl-coated polyester industrial screen.

What the screen does is diffuse all pressure and allow swath to fall instead of deflecting out the sides.

By using this approach, it eliminates the need of a frame to contain a solid shield. It also gives you the option of having it quick attach and detach.
